An active matrix type display panel is a hold type display panel which has
a plurality of pixels arranged in a matrix form, and holds and displays
an electrical signal pixel by pixel for a predetermined time. A frame
rate conversion circuit converts a video signal having a first vertical
frequency (60 Hz) into a video signal having a second vertical frequency
(120 Hz) which is m/n-fold (wherein m is an integer of 2 or more, n is an
integer of 1 or more, and conditions of m>n are satisfied) of the
first vertical frequency. A time base emphasizing circuit subjects an
output from the frame rate conversion circuit to time base emphasis. A
drive circuit displays the video signal having the second vertical
frequency in a display panel.
